SAN FRANCISCO--(BUSINESS WIRE)--May 7, 2015--
FibroGen, Inc. (Nasdaq:FGEN) announced today that it has received a $15
million milestone payment from AstraZeneca AB (“AstraZeneca”), triggered
by the completion of roxadustat non-clinical carcinogenicity studies. In
two separate two-year carcinogenicity studies, in rats and in mice,
there was no evidence of a roxadustat-related effect on mortality or
carcinogenicity.
Non-clinical carcinogenicity data are a standard component of novel
small molecule drug development and are typically required by the U.S.
Food and Drug Administration and other regulatory agencies as part of
the drug approval process.
Roxadustat is a hypoxia-inducible factor prolyl hydroxylase inhibitor
(HIF-PHI) that acts by stimulating the body’s natural pathway of red
blood cell production, or erythropoiesis. Roxadustat is the first
HIF-PHI to enter Phase 3 clinical development and represents a novel
approach to the treatment of anemia in patients with chronic kidney
disease (CKD), with the potential to address the considerable unmet
medical need for an effective treatment for anemia that offers the
convenience of oral administration and an improved safety profile as
compared to current standards of care.
Roxadustat is currently in Phase 3 global development for the treatment
of anemia in patients with chronic kidney disease (CKD) on dialysis and
not on dialysis. The global development program is being conducted by
FibroGen and its partners, AstraZeneca and Astellas Pharma Inc.
Approximately 8,000 CKD patients will be enrolled in 10 clinical trials.
Regulatory filings are expected to be submitted in 2016 for China and in
2018 for the US.
About FibroGen
FibroGen is a research-based biopharmaceutical company focused on the
discovery, development and commercialization of novel therapeutics to
treat serious unmet medical needs. The company utilizes its extensive
experience in fibrosis and hypoxia-inducible factor (HIF) biology to
generate multiple programs targeting various therapeutic areas. Its most
advanced product candidate, roxadustat, or FG-4592, is an oral small
molecule inhibitor of HIF prolyl hydroxylases, or HIF-PHs, in Phase 3
clinical development for the treatment of anemia in CKD. A second
product candidate, FG-3019, is a monoclonal antibody in Phase 2 clinical
development for the treatment of idiopathic pulmonary fibrosis (IPF),
pancreatic cancer and liver fibrosis.
